Overhelping.

Overhelping occurs when one attempts to spoil an observer's impression of a performer by explicitly helping the performer achieve a goal, thereby inviting the observer to attribute the performer's success to the help. The results of 4 experiments suggest (a) that people are most likely to overhelp when they believe that their interventions will be ineffective but will be considered effective by observers and (b) that when either of these beliefs is wrong, the strategy will backfire. The results point to an intervention principle that predicts how and when people may most effectively influence a performance so as to shape observer's inferences about the performer.
